抄録

Concentrations of immunoreactive plasma gonadotropin (c-GtH) were measured for goldfish kept at conditions of temperature held constant or increasing between 10 and 30 °C, between February and July. At temperatures of 17 °C or above the levels of plasma c-GtH were significantly (P <0.005) higher during April and May than at 10 °C. In April the pituitary concentration of c-GtH was maximum for fish held at 17 °C or above and the minimum for fish held below 17 °C, but in June the situation was reversed. A study of the gonads showed that spermatogenesis is faster at 17–24 °C than at 10 °C, but at 30 °C spermatogenic activity was inhibited.
